Abstract

Selon l'invention, un signal optique est émis, optiquement amplifié et filtré, puis reçu. La filtration optique élimine le bruit optique, notamment le bruit par émission spontanée amplifiée, et elle est configurée de façon à passer un signal optique à bande latérale unique, une filtration multimodale pouvant être appliquée. Il est possible de détecter un changement dans le signal optique, et les caractéristiques de la filtration optique peuvent être changées sur la base du changement détecté.
